I have heard of some issues with single file snap restore in 'older' version...maybe fixed in 8.2?, I am not sure. I always use ndmpcopy over snapstore when possible. I would suggest that as an alternative, though I know that does not exactly answer your question.

Hi all;
Running 8.1.2P4 in 7-Mode on an IBM N6240. We initiated a couple of single-file snaprestores which ran for 15+ hours on some busy SATA-based aggregates). During that time, we experienced intermittent issues connecting to the NFS services on this filer. Issues would clear up after a while (minutes or tens of minutes) and then return an hour or so later.
We killed the snaprestores during one of the outages and observed a full recovery of the NFS service. It may have been coincidental.
Anyone aware of snaprestore (specifically, single-file restores) causing cascading impacts?
OnCommand doesn't show any additional spike in CPU, disk activity, etc....
